Ping-Pong balls make for great STEM challenge materials. Our Ping-Pong Problem-Solving STEAM activity challenges students to build a structure that will hold a Ping-Pong ball cantilevered as far away as possible. Have them work together in groups to solve the challenge in under 8 minutes and see which group can earn the most points!
Not able to meet in person? Have your students work together virtually in groups to solve the challenge. One student in each group can build the structure based on collaborative direction from their group members.
